  • There isn’t a standard that is broadly-adopted, but NUT (https://networkupstools.org/) has reverse-engineered drivers for nearly every UPS out there, usually each brand has their standard so as long as the brand is supported it will work. (NUT is also what TrueNAS, Synology, QNAP, etc use internally for their UPS support)

    I’ve had good luck with using NUT with APC UPSes (both consumer models and buying used enterprise rack-mount models).

    One cool thing you can do with NUT is share the UPS state over the network, so that multiple machines can respond to the power state instead of just the machine that is plugged in via USB directly.


  • When I was following Synology communities closer, the common wisdom was that the expansion units weren’t great in either performance, stability or cost, and you were better off buying a new, bigger unit and then selling your old one used to recoup the cost difference.

    I’m also in the same position, I have a DS918+ that is full. It’s also 6 years old and probably on the tail end of getting software updates so I’m weighing my choices…






  • Here are some results if anyone comes across this thread in the future.

    The baseline result I need to achieve is a speedtest result of 7.5 Gbit that the ISP’s rental router gives me.

    I ended up picking up:

    • Lenovo ThinkCentre Tiny M720q, Core i3 8100T, 8 GB RAM ($70)
    • Huawei SP310 (Intel X520-DA2/82599) dual 10 Gbit NIC ($20)
    • 16x PCIe riser + Network Card Bracket ($20)

    Initially I installed pfSense. I ran iperf3 to just get an initial sanity check that the PCIe card/wiring was working right but was getting results between 3-7 Gbit with the CPU pegging at 50%. Some quick googling returned results like “you can’t run iperf on pfSense!” and “pfSense isn’t a router, why do people keep using it as a router, it’s a firewall!”, so I decided to switch to OpenWRT since the Linux side of things always seems to make more sense.

    On OpenWRT, iperf easily hit 9 Gbit with like the CPU at 95% idle.

    It took like 2 hours to configure the weird IPIP6 tunnel my ISP uses for IPv4, but once it was set up, the machine has no trouble routing the same 7.5 Gbit speedtest the ISP router managed, with the CPU usage at 78% idle (the remainder in “sirq”)

    Power consumption:

    • ISP router draws a solid 16W both when it’s idle and when there is 7.5 Gbit of traffic
    • The M720q draws 16W when idle and up to 29W when there is 7.5Gbit of traffic. This is with two copper SFP+
    • This is without tweaking any power saving options in BIOS etc




  • The low power consumption is one of the reasons I was attracted to the ThinkCenter M720q devices. It definitely wouldn’t be worth it if I had to build some tower PC or run a Xeon server!

    The ISP router I’m getting is 10 Gbit (on WAN and one LAN port, the rest are 1 Gbit), but the configuration seems limited and it’s a $5/mo rental tacked onto the bill.

    I think I can live without IDS/IPS, in all the time I used it on UniFi, it never gave me any actionable info, so hopefully that helps me with performance.

    That’s interesting about the 10Gbit ethernet cards. Is that with something like a Mellanox or some other card? My NAS is going to be stuck on 2.5 Gbit since it’s just a Synology.



  • Yeah I’m not ordering anything until I have the connection up and running, which is why I opted to rent the ISP router to begin with, but looking at results online that others on the same ISP have posted, I can probably expect up to around 7 Gbit real-world so I’ve been thinking that I will at least want something better than the standard 1 Gbit or even 2.5 Gbit stuff out there, hence why I’m trying to research what the hardware requirements actually are!







  • For anyone who’s not in the Synology ecosystem, this is what the release notes are:

    Starting from this version, the processing of media files using HEVC (H.265), AVC (H.264), and VC-1 codecs will be transitioned from the server to end devices to reduce unnecessary resource usage on the system and enhance system efficiency. These codecs are widespread on end devices such as smartphones, tablets, computers, and smart TVs. If the end device does not support the required codecs, the use of media files may be limited.

    This mostly affects things like streaming to a TV, streaming box or tablet with limited codec support.

    When watching videos on Linux, the support on the NAS itself doesn’t matter, just the support only your PC. When opening videos over SMB in dolphin, the codec support on the NAS does not come into play. The thumbnails are generated by your PC.

    Just install VLC on your PC and it will play whatever you throw at it, regardless of OS codecs. I would not re-encode anything.

    edit: It looks like the biggest impact is using Synology Photos - it can’t generate thumbnails for HEIF photos/HEIC videos anymore


  • The logic was just that when UNIX was originally evolving, they ran out of disk space on their PDP-11 and had to start moving less-essential binaries to a different disk. That’s why it’s “/usr/” which was originally for user data but that disk happened to have free space.

    Any other explanation is just retcon. Some distros try to simplify things.

    I literally said it has nothing to do with Photoshop - if you shoot a photo on your iPhone or Google Pixel it shoots in HDR, and then you just use the built-in editor on your PHONE, it will edit in HDR. Linux is worse than Pixel and iOS stock photo apps at photo editing. I don’t know why you’re obsessed with Photoshop.
